Journal ArticleDOI
Isospin breaking in K -> 3 pi decays III: Bremsstrahlung and fit to experiment
Johan Bijnens,Fredrik Borg +1 more
TL;DR: In this paper, the effects of order G(27)p(2)e(m(u) -m(d)) and G( 27)p2e(e(2)) on the K-to-3-pi system were investigated.
Journal ArticleDOI
Pion-pion scattering at low energy
TL;DR: In this article, the elastic pi-pi scattering amplitude to two loops in chiral perturbation theory has been evaluated in terms of elementary functions and threshold parameters for two sets of coupling constants.
Journal ArticleDOI
Constraining General Two Higgs Doublet Models by the Evolution of Yukawa Couplings
TL;DR: In this paper, the authors studied how general two Higgs doublet models can be constrained by considering their properties under renormalization group evolution of the Yukawa couplings and found that the latter condition can be used to limit the amount of Z2 symmetry breaking allowed in a given model.
Journal ArticleDOI
Electromagnetic corrections in partially quenched chiral perturbation theory
Johan Bijnens,Niclas Danielsson +1 more
TL;DR: In this paper, the same authors introduced photons in partially quenched chiral perturbation theory and calculated the resulting electromagnetic loop-corrections at next-to-leading-order (NLO) for the charged meson masses and decay constants.
Journal ArticleDOI
The $\Delta I=1/2$ Rule in the Chiral Limit
Johan Bijnens,Joaquim Prades +1 more
TL;DR: In this article, the matching between long-distance and short-distance at next-to-leading in $1/N_c$ and show how the scheme-dependence from the two-loop renormalization group running can be treated.
